To evaluate the efficacy of C(3)F(8) gas-assisted pneumatic displacement in the treatment of massive submacular hemorrhage, with and without the use of tissue plasminogen activator (tPA).
Twenty-one eyes of 21 patients with recently developed (up to 10 days) dense submacular hemorrhage underwent intravitreal injection of pure C(3)F(8) gas (0.4-0.5 mL) followed by face-down positioning for pneumatic displacement. Seven of them received additional intravitreal injection of 25-50 microg tPA. The primary etiology of submacular hemorrhage was age-related macular degeneration (n=16), myopic choroidal neovascularization (n=2), retinal arterial macroaneurysm (n=2), and trauma (n=1). Visual acuity and displacement of hemorrhage were the main outcome measures.
Follow-up period was 6-12 months. Effective displacement of hemorrhage was obtained in 20 of 21 patients within 7 days. Final median Snellen visual acuity (0.18) was found significantly improved compared to baseline (0.03) (p<0.001). Visual acuity improvement was similar in both groups (p=0.72).
Intravitreal injection of C(3)F(8) effectively displaced thick submacular hemorrhage and improved visual acuity independently from primary cause. Additional tPA use in this study had no impact on the final outcomes.
评估C(3)F(8)气体辅助气体置换术在治疗大量黄斑下出血时的疗效,同时观察使用和不使用组织纤溶酶原激活剂(tPA)的情况。
21例近期发生(发病10天内)致密黄斑下出血患者的21只眼,接受了玻璃体内注射纯C(3)F(8)气体(0.4 - 0.5 mL),随后面朝下体位进行气体置换。其中7例额外接受了玻璃体内注射25 - 50微克tPA。黄斑下出血的主要病因包括年龄相关性黄斑变性(n = 16)、近视性脉络膜新生血管(n = 2)、视网膜动脉大动脉瘤(n = 2)和外伤(n = 1)。主要观察指标为视力和出血的移位情况。
随访期为6 - 12个月。21例患者中有20例在7天内实现了出血的有效移位。最终平均Snellen视力(0.18)较基线(0.03)显著提高(p < 0.001)。两组的视力改善情况相似(p = 0.72)。
玻璃体内注射C(3)F(8)可有效移位致密的黄斑下出血并提高视力,与主要病因无关。本研究中额外使用tPA对最终结果无影响。
